IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 34,828, dated April 1,1862.

To all whom it may concern:

Beit known that I, JOHN GROss,of Manilla, in the county of Bush andState of Indiana, have invented certain new and useful Improvements inthe Construction and Arrangement of Cultivators; and I do hereby declarethat the following is an exact description thereof, reference beinghadto the accompanying drawings and the letters marked thereon.

Figure 1 is a perspective, and Fig. 2 a sec tional, View, showing theconstruction and general arrangement of the cultivator.

A is the main frame, and supports the two frames B, which are hinged atB. The levers G are attached to the frames B, and gage the angle anddepth of the points D by means of the notched standards E. The bar orrod F is designed to hold the guides G, and is used in laying off groundfor corn-planting, as will be shown. H is the drivers seat. I I are therollers which bear the weight of the machine when moving about and breakthe clods after the points D. The tongue is firmly attached to the frameA.

The following is the operation of the cultivator: In laying off groundfor corn-planting the points D are taken out and one of them placed ineach of the bars in the rear part of the hinged frames B, so as tosetthe proper distance apart for the rows of corn. They are then set tothe depth required for the furrow by means of the levers O and standardsE. The bar F is then attached so as to allow the pendant upon the end tomark the same distance from the points D that the furrows are apart, andwhen the machine has gone once across the field the driver guides themachine so that the pendant runs in the furrow, thus making the spacesequal.

When corn is to be plowed the points D are placed as shown in Fig. 1,the points being kept near the row next to the guards K, which keep thelumps of dirt from covering the corn.

The advantages of this machine may be seen in the simple manner in whichthe parts are combined, its completeness and adjustability.

It will be seen that when the levers Gare placed in the upper notches ofthe standards E the points D are raised free from the ground and themachine rests entirely upon the rollers I I. It will be borne in mindthat this is effected by simply adjusting the parts without detachingthe same, making a complete roller and cultivator, to be used foreitherseparately as a roller by simply raisiugthe'levers to the notchesin the standards E at the top of the same.

What I claim, and desire to secure by Letters Patent, is-

The lever-frame 15, with levers G and adjustable points D, when operatedin connection with the frame A, with guide-bar F, and rollers I I, bymeans of the standards E, the whole being arranged and operated assetforth.
